- Abstract
- Poly(isoprene) (97% cis-1,4 and 3% 3,4) has been pyrolyzed in a carrier stream of helium gas from 315 to 384 deg C. The products were on-line identified and quantitatively analyzed by an interfaced pyrolysis GC peak identification system. The first order rate constant for pyrolysis is 1.1 x 10(-2) sec(-1) at 384 deg C with an overall activation energy of 41 kcal. mole(-1). The main products are iosprene and 1-methyl1-4isopropyenyl cyclohexene.
